Sorting device

System for storing and organizing materials, comprising:

• a storage area (110),
• at least one first layer (100), preferably a plurality of layers, comprising a plurality of storage locations, which are preferably arranged in rows in two horizontal directions perpendicular to one another and serve to accommodate boxes as a storage location for the materials in stacks,
• at least one transport device (130) which has a receiving area for individual boxes or stacks of boxes to or from the storage system,
• a transport system, in particular a rail arrangement, on which the at least one transport device (130) is mounted so that it can be moved from, to and within the storage system (s) and can be delivered to individual stacks of boxes in the storage system (110) and
• a re-sorting device (140) with
• at least one first gripper (142), which is connected to the storage system via the transport system and is designed to pick up one, preferably at least two, particularly preferably any number/subset of boxes from the stack of boxes, lift them and return them again to the transport device or to a different transport device (130),
• at least one second gripper (142), to which the transport device (130) can be delivered in a loading area of the second gripper and is designed to pick up at least a subset of the remaining boxes of the stack from the transport device (130), and
• a movable storage device (150), which can be delivered to the first and/or the second gripper or a loading area of the gripper(s), and is designed to take picked up boxes from the gripper (s) and from the loading area to move the gripper(s) in a separate storage device of the sorting device for tempo-rary storage, whereby the loading area of the gripper(s) is freed up for picking up or delivering boxes to/from a transport device, wherein the picked up boxes can be temporarily stored in the storage device, preferably next to at least one of the grippers.
